Self-Priming Pumps or Suction Line Check Valves

In an ideal pumping scenario, your pump will always be located beneath the fluid level, allowing gravity to easily feed the fluid into the pump, thus completing the priming process. However, when an application calls for the pump to be located above the liquid level, which of these is a more robust and reliable solution: a) a self-priming centrifugal pump or b.) an end suction pump with a check valve? For the answer, check out our latest Centrifugal Pump Minute.

Maintaining Alignment on ANSI Centrifugal Pumps

One of the primary causes of centrifugal pump vibration is misalignment, but this can be controlled by monitoring, and – if necessary – realigning the pump and motor shafts. In fact, not only is pump alignment a critical factor in eliminating pump vibration, but it can also help eliminate other pump problems and avoid total pump failure. In this Centrifugal Pump Minute, we provide the steps pump operators should follow to ensure both the pump and motor shafts are aligned.
